| Abstract: | This paper deals with the influence wear-resisting factors in compound layer of nodular iron with matrix pearlite during gaseous nitro-carburizing.For the compound layer with nitroger distribution the X-ray structuralanalysis, micro-structures of surface layer. The wearing test and variouspreparatory heat-treatment has been made. The results denoted that gaseousnitro-carburizing+high-frequency hardening may inprove the wear resistance. |
